The CUB3Ls are miniature electronic counters. The CUB3L has front panel reset, while the CUB3LR has remote reset. These units fill a wide variety of applications. The CUB3Ls feature a rugged reinforced nylon case that snap-fits into a standard rectangular opening without screws or other hardware. Hook-up is simply a matter of connecting two wires, and since the operating voltage is only 3.6 V and with currents in microamps, almost any kind of wire can be used. No external power is required since the internal batteries provide years of uninterruptible service. In addition to these advantages, the CUB3Ls offer the inherent ruggedness, reliability, and permanence of completely integrated circuitry, embedded in a single monolithic, silicon, micro-chip.
